Example 3

On the basis of the structure of the embodiment 1, in order to facilitate the quick separation of the sausage casing on the transferring tool out of the meat paste discharging pipe 7 and realize the knotting of the sausage casing. The embodiment designs a casing knotting mechanism 6, and the casing knotting mechanism 6 can be used as a part of a quick-change tool kit and matched with a transshipment tool for use.

The sausage casing knotting mechanism 6 of the present embodiment comprises a rotating sleeve 61, a baffle 63, an arm seat 62, a clamping arm 64, a driving mechanism 67 and the like.

The rotating sleeve 61 can be sleeved outside the muddy meat discharging pipe 7 and can rotate relative to the muddy meat discharging pipe 7; when the sausage casing is sleeved outside the rotating sleeve 61, the sausage casing outside the rotating sleeve 61 can be driven to rotate by controlling the rotation of the rotating sleeve 61, the sausage casing with the meat paste part cannot rotate due to resistance or the hand holding of workers and the like, and under the double effects, the sausage casing can form a twisted knot at the outlet of the meat paste discharging pipe 7, so that the sausage knotting effect is formed. When the transshipment tooling is used, the sausage casing can be kept outside the rotating sleeve 61 when the transshipment tooling is sleeved outside the rotating sleeve 61 and the first sleeve clack 1 and the second sleeve clack 2 are successively detached; the drive mechanism 67 is capable of controlling the rotation of the rotating sleeve 61 and of causing the casing to produce a twisted knot.

The driving mechanism 67 comprises a driven wheel 671, a transmission belt 672, a driving wheel 673 and a driving motor 674; the driven wheel 671 is coaxially connected to the rear end of the rotating sleeve 61, the driving wheel 673 is connected to the rotating shaft of the driving motor 674, and the transmission belt 672 is connected between the driven wheel 671 and the driving wheel 673, so that the rotating sleeve 61 can be driven to rotate after the driving motor 674 is started.

The outer side walls of two opposite sides of the rotating sleeve 61 are respectively provided with a blocking piece 63, and the blocking pieces 63 can extend into the guide notches, so that when the two sleeve flaps are pulled back along the rotating sleeve 61, the movement of the sausage casing can be blocked. The outer side walls of two opposite sides of the rotating sleeve 61 are respectively provided with an arm seat 62, and the end part of each arm seat 62 is connected with a connecting arm 65; the free end of the connecting arm 65 is connected with a clamping arm 64, and an extension spring 66 is connected between the connecting arm 65 and the arm seat 62; the clip arms 64 are capable of compressing the casing in a radial direction of the rotating sleeve 61, thereby providing resistance to the casing being pulled out of the rotating sleeve 61. When the connecting arm 65 rotates to the front side or the rear side of the arm seat 62, the extension spring 66 can maintain the position of the connecting arm 65, thereby facilitating the use and operation of the clamping arm 64.

When the sausage casing knotting mechanism 6 of the embodiment is used, a transfer platform 5 can be placed at the outlet side of the meat paste discharging pipe 7, and then the tying treatment of the knotted part is manually performed on the transfer platform 5. When the transshipment tool is sleeved at the front end of the rotating sleeve 61, the blocking piece 63 relatively extends into the guiding notch, at this time, the blocking piece 63 can block the casing from moving backwards, and then when the clamping arm 64 rotates to the outside of the rotating sleeve 61, the casing can be positioned, so that the casing is prevented from following when the first sleeve flap 1 and the second sleeve flap 2 are pulled out backwards, and the casing can be kept outside the rotating sleeve 61 after the first sleeve flap 1 and the second sleeve flap 2 are all pulled out.

When the meat paste is filled into the sausage casing at the front end of the meat paste discharging pipe 7 through the meat paste discharging pipe 7, the sausage casing is pushed to move forwards and is pulled out of the rotating sleeve 61, and the rotating sleeve 61 can be controlled to rotate once every time a section of sausage is filled, the rotating sleeve can rotate for 1.5-2 circles once, so that the sausage casing can be knotted at the outlet of the meat paste discharging pipe 7, and a worker can conveniently perform rope tying operation at the middle rotating platform 5 according to the formed knots.

The above examples are merely for clearly illustrating the examples and are not intended to limit the embodiments; this need not be, nor should it be exhaustive of all embodiments. And obvious variations or modifications of this technology may be resorted to while remaining within the scope of the technology.
